Abstract: In the present paper, a probabilistic method for stochastic modelling and performance evaluation of a pulping unit is suggested. The paper plant consists of various units like feeding, pulping system, bleaching system, screening system and paper production system. Pulping unit is one of the paper plant's most significant functional units, consisting of five repairable subsystems which are arranged in series. Using Markov process, differential equations are created after drawing transition diagram and these models are then used to discover the pulping unit's availability by considering the repair and failure information acquired from maintenance personnel. Based upon the various performance values for critical system using analytic hierarchy process (AHP), the priority weights of the considered criteria are found and ranking of failure causes are performed using vlse kriterijumska optimizacija kompromisno resenje (VIKOR) to find the most critical component.

Keywords: Markovian; stochastic modelling; multi-criteria decision making; MCDM; availability; AHP-VIKOR; maintenance planning.
